Schlage C604-234 – Frequently Asked Questions

1) Which Schlage mailbox cylinders does the C604-234 washer spacer fit?
The C604-234 is made for Schlage 20-033, 20-066, 20-067 and 20-069 mailbox cylinders. If the cylinder you are servicing is one of those four, this is the matching OEM spacer. For any other Schlage cylinder series, it is not the specified part.
2) What does the washer actually do in a mailbox cylinder install?
It acts as a spacer behind the cylinder, taking up slack so the cylinder seats square and stays aligned in the mailbox door during assembly. Without it the cylinder can sit loose or cocked in the hole, which shows up later as a key that binds or a cam that does not throw cleanly.
3) Is the C604-234 a genuine Schlage part or an aftermarket washer?
Genuine Schlage OEM, built to Schlage's own specification for the 20-series mailbox cylinders. That matters on a spacer because thickness is the whole point of the part; a generic washer of the wrong gauge changes how far the cylinder sits proud of the mailbox door.
4) Do I need to modify anything to install the C604-234 washer?
No. It is a drop-in replacement for the original washer in a Schlage 20-033, 20-066, 20-067 or 20-069 cylinder assembly, so it goes back the way the original came out with no drilling or filing.
5) Does the C604-234 come with the mailbox cylinder, or is it just the washer?
Just the washer spacer. The C604-234 is an installation accessory on its own, so if you are replacing a whole mailbox lock you still need the 20-033, 20-066, 20-067 or 20-069 cylinder, plus its cam and nut, ordered separately.
6) Is this washer suitable for apartment and office mailbank hardware, or is it residential only?
It is a commercial-rated component, and the typical use is exactly that: apartment common-area mailboxes, office mail centers, campus and municipal mailrooms, anywhere Schlage 20-series mailbox cylinders are in service. Property managers keeping a bin of these on hand for turnovers is the normal case.
